About Integer:

Our first experience with math usually deals exclusively with the whole numbers: 0,1,2,3,… Once we have mastered operations with the whole numbers, we start talking about the integers …-2,-1,0,1,2,… The integers include all of the whole numbers and their opposites.


Test Objectives
  • Demonstrate the ability to determine the relationship between two integers
  • Demonstrate the ability to find the opposite (additive inverse) of a number
  • Demonstrate the ability to simplify an expression with multiple negative signs
